My Mom has been diagnosed with Stage 3 breast cancer. She is 70 years old and has diabetes (around 110 fasting) and hypertension (140/70). She takes Glycomet GP-1 for diabetes and olvance H20 for Blood pressure. She had swelling in her right arm apparently due to the tumor compressing the veins. we would not have known about cancer if not for the swelling in the right arm. Doctor initially said my Mom needs to undergo neoadjuvant Chemotherapy to shrink the tumor before surgery. She is currently undergoing chemotherapy and has completed 3rd cycle of FAC regimen 2 days back. Doctor has suggested to do a 2D Echo after 3 weeks from 3rd Cycle, but there is no recommendation to do CT scan of something else to check the chemo response. She is not having much side effects at all. The Swelling has reduced a bit, but has not gone away completely. I am very worried if she is getting the right treatment. The PET CT scan says supraclavicular node positive with SUV of 10 and dimension of 19mm x 20mm. I am very worried about involvement of Supraclavicular Lymph Node. When I run my fingers over it, it moves a lot actually. Is there a chance of this being benign? I have read that cancer tumors are normally irregular, hard and immovable. Please let me know.
Here are the details of tests
1. lump in axillary tail 49mm X 36 mm SUV 14
2. Supraclavicular lymph node 19 X 20mm SUV 10
No other metabolic activity anywhere else. Nothing in Skin, breastbone or chest wall.
3. grade 1 invasive ductal carcinoma
4. ER +ve 80%, PR +ve 20% HER2 -ve
5. Ki-67 - 20%
6. Nothing reported in Chest Xray, Ultrasound of pelvis and Abdomen, liver
Please help me with some information on this.
